The invention belongs to the technical field of degradable packaging bags, and discloses a degradable
green environment-friendly packaging bag for calponin transfer and a preparation method thereof.The packaging bag is composed of a
contact layer, a buffer layer, an intelligent
temperature control layer, a
blocking layer and a reinforcing layer, the
contact layer is made of silk
fibroin grafted modified
nanocellulose, the buffer layer is made of
polyurethane foam, and the intelligent
temperature control layer is made of
polyurethane foam. The intelligent
temperature control layer is prepared by mixing a
starch-based
composite material and an n-
octadecane / expanded
graphite composite phase change material, the
barrier layer is prepared from a modified
montmorillonite /
polyvinyl alcohol composite material, and the reinforcing layer is prepared by weaving base cloth with PLA / PHA composite fibers and compounding a bamboo
fiber antibacterial film on the surface; according to the technical scheme, the functions of all the
layers accurately meet the requirements of
calcium protein transport and form a synergistic effect, the
protein adsorption rate is greatly reduced, denaturation and inactivation of
calcium protein due to adsorption are avoided, the
biocompatibility is guaranteed, a qualified
raw material basis is provided for subsequent detection, diagnosis and
drug research and development, the barrier property is improved, the
calcium protein transport waste rate is remarkably reduced, and the production cost is reduced. The transportation success rate is greatly improved.
